Question

During normal oil service at Jiffy Lube, my mechanic was checking various levels and topping off. When he was checking the radiator he found oil in the water. I checked and sure enough it appears as if the engine is venting oil into the radiator from someplace. Any ideas? A mechanic friend suggested it my be an oil cooler gone bad. Any thoughts and if so any estimate on cost? The car doesn't smoke to I don't believe it is a head gasket.

  Either the power steering oil cooler of engine oil cooler.
  None of which i have ever seen leak through, best to have the mechanic look at it.
  Surprised they didn't look into it.

  Could also be a head gasket. Has to be leaking somewhere where oil and coolant come close to each other.
